Su01a Temperatures during melting/solidification of wax

The temperatures during melting and solidification can easily be measured:
* Left: Remove the wick from the molten candle wax a tea warmer.
* Middle: Stirr in the wax with a themometer until the solid wax appears at the surface.
* Right Observation: The thermometer reads 48 °C as long as liquid and solid wax are present
  This temeparture was 55°C, when bea wax or ordinary candle wax were used.
Explanation: 48°C is the melting point  of the candle wax used.
The heat supplied during melting is consumed for transfering wax into a liquid.
This heat is released during solidification resulting in a constant temperature.
